I just spent 3 hours in the subway in Stockholm. No, it wasn’t stuck. No, I didn’t get lost. No, I wasn’t held hostage. I actually spent 3 hours in the subway on purpose.

When I scoured the internet and my AFAR phone app for ideas on free or cheap things I could do in Stockholm, I came across this:

“The Stockholm subway system is said to be the world’s longest art exhibit – 110 kilometers long.”

This is probably the last place you’d expect to find Stockholm art. Now my interest was peaked. First, I love transportation. Second, I like art. Third, I love quirky superlative travel attractions. Fourth, I already had a subway ticket.
